Linear IgA Bullous Dermatosis

JJP Biologics has received a positive conclusion on the Clinical Trial Application assessment for a Phase I Study of a potential first-in-class anti-CD89 antagonist, JJP-1212 monoclonal antibody for the treatment of various IgA-mediated autoimmune- and fibrotic diseases. WARSAW, Poland--(BUSINESS WIRE)-- JJP Biologics, a private biopharmaceutical company developing innovative antibody-based therapies, announces a positive decision, issued by the European Medicines Agency, on the Clinical Trial Application to conduct a phase I clinical study in healthy participants (EudraCT: 2023-508661-33-00) with their potential first-in-class anti-CD89 antagonist, JJP-1212. Up to date, JJP Biologics is the first Polish company to receive approval to perform the First-in-Human clinical trial with a novel therapeutic monoclonal antibody. The Phase I trial will be executed in Poland. The study endpoints are designed for a comprehensive evaluation of the treatment's safety profile. The drug will be administered via intravenous infusion in single and multiple ascending dose cohorts. Population size was determined as 48 healthy adult volunteers. The study results will provide data on the safety and tolerability of JJP-1212, and full PK/PD profiles that subsequently enable the determination of optimal treatment regimens in future studies with patient populations. JJP Biologics intends to use Phase I read-outs as supporting data for a set of Phase II trials, in a range of therapeutic areas, and regions (including EU and the US). “I clearly remember the day when, Prof. Marjolein van Egmond, VU University Medical Center Amsterdam and Scientific Advisory Board member at JJP Biologics, told me about the exciting biology of the IgA-CD89 axis and its pathological consequences in autoimmunity. Stratification of patients can easily be achieved by measuring IgA autoantibodies beyond IgG and IgM levels. While safety data are still needed, this decision is an important milestone for patients suffering from IgA-mediated autoimmune or fibrotic diseases and validates the preclinical package of JJP-1212. I am very grateful towards the JJP Biologics team for all their efforts and the Starak family for their continued trust and support.” - Louis Boon, Ph.D., CSO and Management Board Member at JJP Biologics. According to Paweł Szczepański, COO and Management Board Member at JJP Biologics - “This is a historically unprecedented approval of a first-in-human clinical trial for a novel large molecule therapy from Poland. It forms a landmark that will further strengthen the position of the Polish biotech sector on the global map blazing the trail for many innovative therapies to come from this part of Europe. Including the next ones from the development platform of JJP Biologics.” “At JJP Biologics, we value science that helps to improve outcomes for rare-disease patients via delivery of innovative treatments. The recently approved study is ambitiously designed to swiftly build a foundation for further development to offer new treatment options for those living with high-burden autoimmune disorders.” – Dawid Łyżwa, Ph.D., Head of Clinical Development at JJP Biologics. “Expected study results will not only validate the safety but also contribute to deciding on extension of JJP‑1212’s development scope.” “I am delighted to hear that JJP Biologics is now starting its clinical program striving for delivery of a first-in-class treatment for IgA-mediated disease. I hope that JJP-1212-01-01 read-outs will deliver a strong foundation for further clinical development in various therapeutic areas, well beyond dermatology.” – Prof. Christoph Hammers, University Medical Center Regensburg, Germany. “As JJP-1212 targets the underlying cause of the disease – in case of success, it will be a valuable treatment option for a set of conditions with high unmet medical needs and may drive the clinical remissions for the multiplicity of severe patients. JJP Biologics demonstrates the commitment and devotion to the safety and wellbeing of patients.” – Prof. Pascal Joly, Rouen University Hospital, France JJP-1212 JJP-1212 is a first-in-class IgG4-κ anti-CD89 antagonist that is being developed to treat autoimmune and fibrotic diseases in which IgA autoantibodies are a key element of the disease pathophysiology. Alongside Linear IgA Bullous Dermatosis (LABD), JJP-1212 is being developed for a wide range of autoimmune- and fibrotic diseases where IgA is known to have significant pathogenic involvement (e.g. rheumatoid arthritis, axial spondyloarthritis, systemic lupus erythematosus, neutrophilic asthma, chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, cystic fibrosis, hidradenitis suppurativa, nonalcoholic steatohepatitis, IgA nephropathy, IgA vasculitis). JJP Biologics is exploring the development of companion diagnostics in various indications using serum IgA autoantibodies as biomarkers for personalized treatment with JJP-1212. LABD LABD, also known as Linear IgA Bullous Dermatosis or linear IgA disease, is a chronic, debilitating disease that leads to skin separation, blistering, and in extreme cases, vision loss. Currently, no medicinal products are approved for the treatment of LABD in the European Union. The estimated incidence of LABD ranges from 0.2 to 2.3 cases per 1,000,000 people per year. JJP Biologics JJP Biologics is a clinical-stage biotechnology company that specializes in the development of therapeutic monoclonal antibodies accompanied by companion diagnostics for personalized treatment. JJP Biologics pursues the development of its product candidates as well as projects executed in cooperation with scientific partners. The company’s programs target general immune pathways that have applications in autoimmune diseases and cancer. JJP Biologics’ pipeline includes the most advanced JJP-1212, a potential first-in-class anti-CD89 antagonist for the treatment of autoimmune- and fibrotic diseases, and JJP-1008, a potential first-in-class anti-CD270 checkpoint inhibitor, for solid tumors. JJP-1212 Project is co-financed by the state budget by the Polish Medical Research Agency (No: 2022/ABM/05/00011). JJP Biologics is a privately funded biotech, partially financed from programs run by the Polish Medical Research Agency.

Norepinephrine Bitartrate in 5% Dextrose Injection Indications Norepinephrine Bitartrate in Dextrose Injection is indicated to raise blood pressure in adult patients with severe, acute hypotension. Important Risk Information Contraindications: None. Tissue Ischemia: Administration of Norepinephrine Bitartrate in Dextrose Injection to patients who are hypotensive from hypovolemia can result in severe peripheral and visceral vasoconstriction, decreased renal perfusion and reduced urine output, tissue hypoxia, lactic acidosis, and reduced systemic blood flow despite “normal” blood pressure. Address hypovolemia prior to initiating Norepinephrine Bitartrate in Dextrose Injection. Avoid use in patients with mesenteric or peripheral vascular thrombosis, as this may increase ischemia and extend the area of infarction. Gangrene of the extremities has occurred in patients with occlusive or thrombotic vascular disease or who received prolonged or high dose infusions. Monitor for changes to the skin of the extremities in susceptible patients. Extravasation of Norepinephrine Bitartrate in Dextrose Injection may cause necrosis and sloughing of surrounding tissue. To reduce the risk of extravasation, infuse into a large vein, check the infusion site frequently for free flow, and monitor for signs of extravasation. Avoid administration into the veins in the leg in elderly patients. Emergency Treatment of Extravasation: Infiltrate the ischemic area as soon as possible, using a syringe with a fine hypodermic needle with 5 to 10 mg of phentolamine mesylate in 10 to 15 mL of 0.9% Sodium Chloride Injection in adults. Hypotension after Abrupt Discontinuation: Sudden cessation of the infusion rate may result in marked hypotension. When discontinuing the infusion, gradually reduce the infusion rate while expanding blood volume with intravenous fluids. Cardiac Arrhythmias: Norepinephrine Bitartrate in Dextrose Injection elevates intracellular calcium concentrations and may cause arrhythmias, particularly in the setting of hypoxia or hypercarbia. Perform continuous cardiac monitoring of patients with arrhythmias. Elderly Patients: May be at a greater risk of developing adverse reactions. Adverse Reactions: Most common adverse reactions are hypertension and bradycardia. Drug Interactions: Co-administration of Norepinephrine Bitartrate in Dextrose Injection with monoamine oxidase (MAO) inhibitors or other drugs with MAO-inhibiting properties (e.g., linezolid) or with tricyclic antidepressants can cause severe, prolonged hypertension. Anti-diabetics: Norepinephrine Bitartrate in Dextrose Injection can decrease insulin sensitivity and raise blood glucose. Concomitant use of Norepinephrine Bitartrate in Dextrose Injection with halogenated anesthetics may lead to ventricular tachycardia or ventricular fibrillation. Monitor cardiac rhythm in patients receiving concomitant halogenated anesthetics. Please see accompanying full Prescribing Information for Norepinephrine Bitartrate in 5% Dextrose Injection. Vasopressin in 0.9% Sodium Chloride Injection Indications Vasopressin in Sodium Chloride Injection is indicated to increase blood pressure in adults with vasodilatory shock who remain hypotensive despite fluids and catecholamines. Important Risk Information Contraindications: Vasopressin in Sodium Chloride Injection is contraindicated in patients with a known allergy or hypersensitivity to 8-L-arginine vasopressin. Worsening Cardiac Function: A decrease in cardiac index may be observed with the use of vasopressin. Reversible Diabetes Insipidus: Patients may experience reversible diabetes insipidus, manifested by the development of polyuria, a dilute urine, and hypernatremia, after cessation of treatment with vasopressin. Monitor serum electrolytes, fluid status and urine output after vasopressin discontinuation. Some patients may require readministration of vasopressin or administration of desmopressin to correct fluid and electrolyte shifts. Adverse Reactions: The most common adverse reactions include decreased cardiac output, bradycardia, tachyarrhythmias, hyponatremia and ischemia (coronary, mesenteric, skin, digital). Drug Interactions: Pressor effects of catecholamines and Vasopressin in Sodium Chloride Injection are expected to be additive. Indomethacin may prolong effects of Vasopressin in Sodium Chloride Injection. Co-administration of ganglionic blockers or drugs causing SIADH (syndrome of inappropriate antidiuretic hormone secretion) may increase the pressor response. Co-administration of drugs causing diabetes insipidus may decrease the pressor response. Pregnancy: May induce tonic uterine contractions that could threaten the continuation of pregnancy. Please see accompanying full Prescribing Information for Vasopressin in 0.9% Sodium Chloride Injection. Vancomycin Injection, USP in 5% Dextrose Indications Vancomycin is indicated for the treatment of serious or severe infections caused by susceptible strains of methicillin-resistant (beta-lactam-resistant) staphylococci. It is indicated for penicillin-allergic patients, for patients who cannot receive or who have failed to respond to other drugs, and for infections caused by vancomycin-susceptible organisms that are resistant to other antimicrobial drugs. Vancomycin is effective in the treatment of: Infective Endocarditis (staphylococcal endocarditis; endocarditis caused by Streptococcus viridans or S. bovis, alone or in combination with an aminoglycoside; endocarditis caused by enterococci (e.g., E. faecalis), only in combination with an aminoglycoside; diphtheroid endocarditis; early-onset prosthetic valve endocarditis caused by S. epidermidis or diphtheroids in combination with either rifampin, an aminoglycoside, or both) Septicemia Skin and Skin Structure Infections Bone Infections Lower Respiratory Tract Infections To reduce the development of drug-resistant bacteria and maintain the effectiveness of vancomycin and other antibacterial drugs, vancomycin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. Important Risk Information Contraindications: Vancomycin is contraindicated in patients with known hypersensitivity to this antibiotic. Solutions containing dextrose may be contraindicated in patients with known allergy to corn or corn products. Infusion Reactions: Rapid bolus administration (e.g., over several minutes) may be associated with exaggerated hypotension, including shock, and, rarely, cardiac arrest. During or soon after rapid infusion of vancomycin, patients may develop anaphylactoid reactions, including hypotension, wheezing, dyspnea, urticaria, or pruritus. Rapid infusion may also cause flushing of the upper body (“vancomycin infusion reaction”) or pain and muscle spasm of the chest and back. Vancomycin should be administered over a period of not less than 60 minutes. Stopping the infusion usually results in prompt cessation of these reactions. Nephrotoxicity: Systemic vancomycin exposure may result in acute kidney injury (AKI). The risk of AKI increases as systemic exposure/serum levels increase. Monitor renal function in all patients; especially with underlying renal impairment, with co-morbidities, and receiving concomitant therapy with a known nephrotoxic drug. Ototoxicity: It may be transient or permanent. It has been reported mostly in patients who have been given excessive doses, who have an underlying hearing loss, or who are receiving concomitant therapy with another ototoxic agent, such as an aminoglycoside. Vancomycin should be used with caution in patients with renal insufficiency. Severe Dermatologic Reactions: Toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome (SJS), drug reaction with eosinophilia and systemic symptoms (DRESS), acute generalized exanthematous pustulosis (AGEP), and linear IgA bullous dermatosis (LABD) have been reported. Cutaneous signs or symptoms reported include skin rashes, mucosal lesions, and blisters. Discontinue vancomycin Injection at the first appearance of signs and symptoms of TEN, SJS, DRESS, AGEP, or LABD. Dosage of vancomycin must be adjusted for patients with renal dysfunction. Clostridioides difficile associated diarrhea (CDAD): May range in severity from mild diarrhea to fatal colitis. CDAD must be considered in all patients who present with diarrhea following antibiotic use. If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile, and surgical evaluation should be instituted as clinically indicated. Hemorrhagic Occlusive Retinal Vasculitis: Including permanent loss of vision, occurred in patients receiving intracameral or intravitreal administration of vancomycin during or after cataract surgery. The safety and efficacy of vancomycin administered by the intracameral or the intravitreal route have not been established. Adverse Reactions: Not already mentioned above, patients have been reported to have neutropenia, phlebitis, drug fever, nausea, chills, and vasculitis in association with administration of vancomycin. Drug Interactions: Anesthetic Agents: Concomitant administration of vancomycin and anesthetic agents has been associated with erythema and histamine-like flushing and anaphylactoid reactions. Monitor renal function in patients receiving vancomycin and concurrent and/or sequential systemic or topical use of other potentially neurotoxic and/or nephrotoxic drugs, such as amphotericin B, aminoglycosides, bacitracin, polymyxin B, colistin, viomycin, or cisplatin. Please see accompanying full Prescribing Information for Vancomycin Injection, USP. Ropivacaine Hydrochloride Injection, USP Indications Ropivacaine Hydrochloride Injection is an amide local anesthetic indicated in adults for the production of local or regional anesthesia for surgery and for acute pain management. Surgical Anesthesia: epidural block for surgery including cesarean section; major nerve block; local infiltration. Acute Pain Management: epidural continuous infusion or intermittent bolus, e.g., postoperative or labor; local infiltration. Important Risk Information Contraindications: Ropivacaine Hydrochloride Injection is contraindicated in patients with a known hypersensitivity to ropivacaine or to any local anesthetic agent of the amide type. General Warning: Delay in proper management of dose-related toxicity, underventilation, and/or altered sensitivity may lead to the development of acidosis, cardiac arrest and, possibly, death. The safe and effective use of local anesthetics depends on proper dosage, correct technique, adequate precautions, and readiness for emergencies. It is essential that aspiration for blood, or cerebrospinal fluid (where applicable), be done prior to injecting any local anesthetic, both the original dose and all subsequent doses, to avoid intravascular or subarachnoid injection. Unintended Intravenous Injection: In performing Ropivacaine Hydrochloride Injection blocks, unintended intravenous injection is possible and may result in cardiac arrhythmia or cardiac arrest. Ropivacaine hydrochloride injection should be administered in incremental doses. It is not recommended for emergency situations, where a fast onset of surgical anesthesia is necessary. Intra-Articular Infusions and Risk of Chondrolysis: Intra-articular infusions of local anesthetics may cause chondrolysis. Ropivacaine Hydrochloride Injection is not approved for this use. Risk of Methemoglobinemia: Patients with glucose-6-phosphate dehydrogenase deficiency, congenital or idiopathic methemoglobinemia, cardiac or pulmonary compromise, infants under 6 months of age, and concurrent exposure to oxidizing agents or their metabolites are more susceptible to developing clinical manifestations of the condition. If local anesthetics must be used in these patients, close monitoring for symptoms and signs of methemoglobinemia is recommended. Signs of methemoglobinemia may occur immediately or may be delayed some hours after exposure. Immediate treatment is required to avert more serious central nervous system and cardiovascular adverse effects, including seizures, coma, arrhythmias, and death. Discontinue ropivacaine hydrochloride injection and any other oxidizing agents. Central Nervous System Toxicity: Careful and constant monitoring of cardiovascular and respiratory vital signs and the patient's state of consciousness should be performed after each local anesthetic injection. Hepatic Disease: Because amide-type local anesthetics such as ropivacaine are metabolized by the liver, these drugs, especially repeat doses, should be used cautiously in patients with hepatic disease. Patients with severe hepatic disease are at a greater risk of developing toxic plasma concentrations. Adverse Reactions: Most common adverse reactions (incidence ≥ 5%) are hypotension, nausea, vomiting, bradycardia, fever, pain, postoperative complications, anemia, paresthesia, headache, pruritus, and back pain. Drug Interactions: Agents structurally related to amide-type local anesthetics: Concurrent use may cause additive effects. Please see accompanying full Prescribing Information for Ropivacaine Hydrochloride Injection, USP. Regadenoson Injection Indications Regadenoson injection is a pharmacologic stress agent indicated for radionuclide myocardial perfusion imaging (MPI) in patients unable to undergo adequate exercise stress. Important Risk Information Contraindications: Do not administer regadenoson injection to patients with: Second- or third-degree AV block, or Sinus node dysfunction, unless these patients have a functioning artificial pacemaker. Myocardial Ischemia: Fatal cardiac events have occurred. Avoid use in patients with symptoms or signs of acute myocardial ischemia, for example unstable angina or cardiovascular instability, who may be at greater risk. Cardiac resuscitation equipment and trained staff should be available before administration. Sinoatrial (SA) and Atrioventricular (AV) Nodal Block: Adenosine receptor agonists, including regadenoson injection, can depress the SA and AV nodes and may cause first-, second- or third-degree AV block, or sinus bradycardia. Atrial Fibrillation/Atrial Flutter: New-onset or recurrent atrial fibrillation with rapid ventricular response and atrial flutter have been reported. Hypersensitivity, Including Anaphylaxis: Anaphylaxis, angioedema, cardiac or respiratory arrest, respiratory distress, decreased oxygen saturation, hypotension, throat tightness, urticaria and rashes have occurred. Have personnel and resuscitative equipment immediately available. Hypotension: Adenosine receptor agonists, including regadenoson injection, induce vasodilation and hypotension. The risk of serious hypotension may be higher in patients with autonomic dysfunction, stenotic valvular heart disease, pericarditis or pericardial effusions, stenotic carotid artery disease with cerebrovascular insufficiency, or hypovolemia. Hypertension: Adenosine receptor agonists, including regadenoson injection, may induce clinically significant increases in blood pressure particularly in patients with a history of hypertension and when the MPI includes low level exercise. Bronchoconstriction: Adenosine receptor agonists, including regadenoson injection, may induce dyspnea, bronchoconstriction and respiratory compromise, especially in patients with chronic obstructive pulmonary disease (COPD) or asthma. Resuscitative measures should be available. Seizure: Regadenoson injection may lower the seizure threshold. New onset or recurrence of convulsive seizures has occurred. Some seizures are prolonged and require urgent anticonvulsive management. Methylxanthine use is not recommended in patients who experience a seizure in association with regadenoson injection. Cerebrovascular Accident (Stroke): Hemorrhagic and ischemic cerebrovascular accidents have occurred. Adverse Reactions: The most common (incidence ≥ 5%) adverse reactions to regadenoson injection are dyspnea, headache, flushing, chest discomfort, dizziness, angina pectoris, chest pain, and nausea. Drug Interactions: Methylxanthines, e.g., caffeine, aminophylline and theophylline, interfere with the activity of regadenoson injection. Aminophylline may be used to attenuate severe and/or persistent adverse reactions to regadenoson injection. Dipyridamole may increase the activity of regadenoson injection. When possible, withhold dipyridamole for at least two days prior to regadenoson injection administration. Please see accompanying full Prescribing Information for Regadenoson Injection.

Antagonist anti-CD89 will be developed for the treatment of Linear IgA Bullous Dermatosis. WARSAW, Poland--(BUSINESS WIRE)-- JJP Biologics, a company that specializes in the development of proprietary biologic agents for personalized medicine approaches, has announced that the European Commission has approved the company’s application for designation of its product candidate JJP-1212 as an orphan medicinal product for treatment of Linear IgA Bullous Dermatosis (LABD). Following the European Medicines Agency’s recommendation, the European Commission has confirmed that the intention to treat this condition with JJP-1212 justified orphan drug status based on in vitro and in vivo non-clinical data showing the reduction in the influx of granulocytes into the basement membrane zone of the skin and reduction of inflammatory biomarkers, addressing the key elements of LABD skin blistering pathogenesis. LABD is a chronically debilitating disease and may lead to blindness and blister formation. Moreover, currently no approved treatments are available for LABD in the European Union. The European Commission has confirmed that, as of the day of submitting the application, LABD could affect approximately 0.3 in 10,000 persons in the European Union.1 “The orphan drug designation of JJP-1212 by the EMA validates the scientific and business choices of JJP Biologics. It was confirmed that JJP-1212 targets the central mechanism in LABD by antagonizing the IgA-CD89 interaction” according to Louis Boon, the Chief Scientific Officer at JJP Biologics. “We are very excited to offer a potential novel therapy for patients suffering from this ultra-rare skin disease with currently unmet needs”.
